ALL Standard valves are supplied with CONTINUOUS DUTY COILS
of the proper class of insulation for the service indicated on the valve.
The coil temperature may become hot after being energized for extended
periods, but it is normal. Smoke or burning odor indicates excessive coil
temperature and should disconnect the power to the coil immediately.
VOLTAGES: Standard: 12-24V DC and 24-110-220-230V/50-60 Hz AC. Voltage
tolerances: +10% –5% for DC, +10%-15% for AC; .
SERVICE LIFE: The service life of the solenoid valve depends on the
operating conditions such as pressure, temperature, type of medium and the
voltage. |

Electrical Coil Connections |
|
For DIN Coil |
To connect DIN coil:
1. Remove the Philip screw from the plastic housing and unplug it from the
DIN coil.
2. From the screw opening, push the terminal block out from the plastic
housing.
3. Note the 1, 2 and ground markings on underside of DIN enclosure.
4. For DC DIN Coil, Connect 1 to Positive, 2 to Negative.
5. For AC DIN Coil, connect 1 to HOT wire, 2 to Neutral wire, and if
required connect ground to ground wire. |
|
For Grommet Coil |
To connect Grommet coil:
1. For DC Coil, connect one of the two wires to Positive, and the
other wire to Negative.
2. For AC Coil, connect one of the two wires to HOT wire, and the other wire
to neutral wire. |

2SO & 2WO Series
2/2 Direct Lift Diaphragm Normally Open Solenoid Valve:
To close: when the valve is energized, it
repels the plunger and forces the plunger to cover the main orifice. The system
pressure builds up on the top of the diaphragm/piston because fluid enters through the bleed
orifice, forcing the diaphragm/piston down until it covers the main orifice
and stops media flow through the valve. The valve can operate at 0 PSI.
To open: when the valve is de-energized, it releases the
plunger and the spring pushes the plunger away from the pilot orifice,
allowing fluid flow out and causing the system pressure
holding the diaphragm/piston closed to drop. As system pressure on the top
of the diaphragm/piston is reduced, full system pressure on the opposite
side of the diaphragm/piston acts to lift the diaphragm/piston away from the
main orifice, which allows the full media flow through the valve.
The valve can operate at 0 PSI.
